Paper Title:
HA Active Coating on Titanium Prepared by Spark Plasma Sintering
  Abstract

Hydroxyapatite (HA) active coatings on Titanium were prepared using Spark Plasma Sintering (SPS). This study focused on the effects of the composition and thickness of coating on its bonding strength and the fracture appearance. The results showed that the Ti20wt%HA80wt% coating on Titanium could be well sintered, and bonding strength was improved from 12 MPa to 29 MPa and to 36 MPa along with the reduction of the coat thickness from 0.3mm to 0.2mm and to 0.1mm respectively. When the coating was treated by passivation, the bonding strength of interface increased largely to 48MPa and 64MPa respectively for HA coating and Ti20wt%HA80wt% coating on Titanium body, which the HA did not disassemble, and metallurgical combination between coating and metal was realized at 1180K.
